摘要
基于区域分裂技术 ,设计了一种使用非均匀网格的LatticeBoltzmann(LB)模型 .其基本思想是 :将流场分解为若干个规则的子区域 ,在每个子区域使用均匀网格上的LB模型求解 ,子区域的边界条件利用插值方法决定 .用该模型对二维圆柱绕流问题进行了模拟 。
A lattice Boltzmann model(LBM)with nonuniform mesh is proposed based on domain decomposition technique.The basic idea is to divide the flow domain into some regular subdomains,and then perform simulations on each subdomain using LBM with uniform mesh.The values on the boundaries of the subdomains are determined by interpolation.The 2-D flow around a cylinder is simulated using the model,the results are also compared with those of other methods.
